Anybody tried FiberSmart or other Renew Life products?

Hello all,
I'm currently taking Dr. Schulze formula 1 and am about to start no.2 soon. However, I'm interested in taking Fiber Smart and EFA's for additional bulk and lubrication. I hear it's a best seller from the Vitamin Shoppe catalog. Is anyone else using this product or other Renew Life products? Cleanse Smart seems interesting too, but I had already purchased my Dr. S products. Also I hear from the parasites board that Paragone working well for many. Any input would be appreciated. TIA
